There is no keystore in my ~/android directory, although the Readme.md 
says I should have a keystore and a release keystore.

I assume that if the person installing has allowed installations from 
unknown sources that this is OK.

Do I need a keystore or can I leave it out and distribute unsigned apk 
files? Presumable that would avoid the problem mentioned above?
